Poly[[bis(pyridin-3-ol)manganese(II)]-di-mu-pyridin-3-olato].

In the title complex, [Mn(C5H4NO)2(C5H5NO)2]n or [Mn(mu-3-PyO)2(3-PyOH)2]n (3-PyO- is the pyridin-3-olate anion and 3-PyOH is pyridin-3-ol), the Mn(II) atom lies on an inversion centre and has octahedral geometry, defined by two N atoms and two deprotonated exocyclic O atoms of symmetry-related pyridin-3-olate ligands [Mn-N = 2.3559 (14) A and Mn-O = 2.1703 (11) A], as well as two N atoms of terminal 3-PyOH ligands [Mn-N = 2.3482 (13) A]. The Mn(II) atoms are bridged by the deprotonated pyridin-3-olate anion into a layer structure, generating sheets in the (-101) plane. These sheets are linked by O-H...O hydrogen bonds. There are also pi-pi and C-H...pi interactions in the crystal structure.
